Hreflang tags

Why use this tool?

Hreflang annotations tell search engines which URLs represent language or regional versions of the same content. This tool generates HTML tags and catches common input mistakes locally.

100% local and secure

Your data stays on your device and is never sent to our servers.

Smart processing

Create and verify web content with settings designed for usable results.

Supported formats

Web formats, metadata, and structured content depending on the available features.

Save time

Get a clean, ready-to-use result in seconds without installing software or configuring a complex workflow.

Fonctionnement

How does this tool work?

Each line maps a language or regional code to an absolute URL. The tool checks the basic syntax, rejects duplicate codes and turns valid entries into link rel="alternate" tags with hreflang attributes. You can also include x-default for a fallback page. Validation is intentionally local: it checks the data you entered but does not fetch remote pages, so reciprocal references and live HTTP status cannot be confirmed.

Use cases

Multilingual website

Create the required tags for several translated versions of one canonical piece of content.

International migration

Prepare annotations while changing domains, folders or localized URL structures.

Technical SEO audit

Catch duplicate codes, invalid URLs and simple configuration mistakes before deployment.

Guide

How to use this tool

  1. 1

    Add localized versions

    Enter one locale=URL line for each language or regional version of the same page.

  2. 2

    Add x-default

    Optionally provide a fallback URL for users who do not match a specific language version.

  3. 3

    Fix and copy

    Resolve any reported issues and copy the generated tags into the page head.

Tips and best practices

  • Use absolute, indexable URLs.
  • Keep hreflang references consistent across every localized variant.
  • Use x-default only when a genuine fallback page exists.

Frequently asked questions

What is x-default for?

x-default can identify the fallback version used when no specific language or regional page is considered the best match for a user.

Should URLs be absolute?

Yes. Hreflang annotations should generally reference absolute, accessible URLs that correspond to the pages you intend search engines to index.

Does this check reciprocal links?

No. The tool validates the entered syntax locally and does not fetch remote pages, so it cannot verify live status codes or reciprocal references.
